Refine Tetramesh

Hi, 

 

Is there a possibility to create a tetramesh from a surface mesh so that it has a smaller mesh size at the surface and larger in the inside. So the mesh size should follow a gradient from outside to inside. The shape I want to mesh is a vertebrae (so no geometrical shape). 

 

thanks, Best

J

    you can keep smaller element size for enclosed volume 2d mesh & bigger element size for tetrahedral mesh.Make sure to have enclosed volume for 3d mesh.

    Hi Rahul,

     

    I try be clearer: 

    I have a surface mesh of a vertebra. Now I want to fill it with tetra solid elements. So far it is easy. However, I want to fill it in a way that I have small tetras at the surface (corresponding to my surface mesh) and larger elements in the center (see ). Is this possible?

     

    Thanks, J

    in case you want to control gradient size, switch tetra parameter to 'user control' and input bigger value for 'growth rate'
